sented in the Atlas of the "Journal de la Navigation Autour du Monde 

 de la fregate la Th6tis et de la corvette 1'Esperance, by Captain Bou- 

 gainville," as also in several other works, referred to in the synonymy, 

 in which its description may likewise be found. We might enlarge 

 upon this subject, had we had at our command Phyllurus inermis and 

 P. miliusii, both belonging, apparently, to the same genus. 



LOG. Specimens were procured in Southeast Australia : they were 

 found about rocks, in the Botanic Garden of Sydney. 



GENUS GONIODACTYLUS, KUHL. 



GEN. CHAR. Back granular, with scattered or serial tubercles. Belly

 parallel longitudinal rows of interfemoral pores. One pair of mental

 Abbild. Amph. 1838. FITZ. Syst. Kept. 1843, 92 & 93. 



OBSERV. The limits here assigned to this genus do not appear to 

 us altogether satisfactory, the scarcity of materials not having per- 

 mitted extending our investigations. 



GONIODACTTLTJS MARMORATUS, Kuhl. 



SPEC. CHAR. Nostrils lateral, situated above the first labial plate. 

 Two pairs of internasals : anterior one largest, and interposed 

 between the rostral and the nostril. Small tubercles scattered over 

 the posterior part of the head, back, sides, limbs, and tail. A tri- 

 angular symphyseal, inclosed by a pair of subtrapezoid mental 

 shields. Brown, marmorated above with black ; beneath unicolor.
